MX3500N SIMULATION 7 – 99
<Set range and default value of each setup>
A to G:1step = 0.1mm
A. Document lead edge reference position: (L1), B. Paper lead
edge positions
Except for A and B, same as the item adjusted with SIM50-01.
The values adjusted with A and B are reflected to the document
lead edge reference position (RRC-A) and all the paper lead edge
positions (RRCB-**).

Operation/Procedure
1) Select the set item with [] and [] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
* If there is any item over [], an active display is made and
item is shifted.
If there is no item over [], the display grays out and the
operation is invalid.
If there is any item under [], an active display is made and
item is shifted.
If there is no item over [], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* When [C] key is pressed, the entered value is cleared.
3) When [EXECUTE] button is pressed, it is highlighted and print-
ing for adjustment is started with the current set value.
After completion of printing, [EXECUTE] button returns to the
normal display.
* When [], [], [OK], [EXECUTE] button, [COLOR], or
[BLACK] key is pressed, the data are saved to EEPROM
and RAM.
* When [C], [CA], [SYSTEM SETTINGS], or [EXECUTE] but-
ton is pressed during printing, the operation is interrupted.
* When the machine returns to the ready state after occur-
rence of an interruption, self print is resumed.
4) Check the adjustment pattern image position.
Measure the dimensions of void area in the right and the left
frame direction of the adjustment pattern to check that the
dimensions are as follows:
If DEN-C = 3.0 ± 2.0mm and DEN-B = 3.0 ± 2.0mm, there is no
need to adjust.
If the values are as shown above, there is no need to adjust.
If not, go to step 5.
5) Change the adjustment values of A (DEN-C) and B (DEN-B).
When the adjustment value of A (DEN-A) is decreased by 1,
the sub scanning direction print start position is shifted toward
the paper lead edge by 0.1mm.
When the adjustment value of B (DEN-B) is decreased by 1,
the paper transport direction print range is extended toward
the rear edge by 0.1mm.
6) Repeat steps 1 to 5 until the conditions of step 4 are satisfied.

The void quantity at the paper rear edge is specified.
* The greater the value is, the greater the void is.
1 to 99 20
G FRONT/REAR FRONT/REAR void quantity adjustment
The void quantities at the left and right edges of paper are specified.
* The greater the value is, the greater the void is.
